The case began at about 8 a.m. Oct. 31, when resident realized that a purse and a GPS tracker had been stolen overnight from a vehicle on Prospect Avenue, police said. The purse contained a credit card and other personal items.

The victim immediately canceled the card, but it had already been used that morning at the CVS on East Blithedale Avenue in Mill Valley and the Chevron gas station in Strawberry, said Sausalito police Lt. Kurtis Skoog. The items they bought at CVS included baby care products, cosmetics and clothing.

The burglars also tried to use the credit card at a Safeway in Mill Valley, but by then the card had been deactivated.

Police found surveillance images showing the women at the CVS and the Chevron. They were using a vehicle that appears to be a black Toyota sports utility vehicle equipped with three sunroofs, Skoog said.

Anyone with information about the women's identities can call the Sausalito Police Department at 289-4170.
